Images in this projection are centered on the equator. Map resolution is constant throughout the image, thus increasing distortion away from the poles. The transformation from latitude and longitude (LAT, LON) in degrees to LINE and SAMPLE is given by the following equations. SCALE = MAP_RESOLUTION SAMPLE = SAMPLE_PROJECTION_OFFSET+SCALE*(LON-CENTER_LONGITUDE)+1 LINE = LINE_PROJECTION_OFFSET-SCALE*(LAT-CENTER_LATITUDE)+1 In the above definitions, integral values of LINE and SAMPLE correspond to the center of a pixel, and the top left image pixel has LINE=1 and SAMPLE=1. LAT and LON are the latitude and longitude of a given spot on the surface in degrees. LINE_PROJECTION_OFFSET is the image line number minus one on which the map projection origin occurs. The map projection origin is the intersection of the equator and the projection longitude CENTER_LONGITUDE. SAMPLE_PROJECTION_OFFSET is the sample number minus one on which the map projection origin occurs. CENTER_LATITUDE is the value of the projection latitude in degrees, which is typically the latitude that passes through the center of the projection. CENTER_LONGITUDE is the value of the projection longitude in degrees, which is typically the longitude that passes through the center of the projection. MAP_RESOLUTION is the number of pixels per degree at the projection origin. For these products, Jupiter System 3 longitude and planetographic latitude are used. The prime meridian is defined per Archinal et al, 'Report of the IAU Working Group on Cartographic Coordinates and Rotational Elements: 2009 [ARCHINAL2010].'
